can cause a change in the way the graphs look. See the Remarks section of the
axes description for more information.
Examples The following surface plot of the function z xe is useful to illustrate
the data aspect ratio. First plot the function over the range –2 ≤ x ≤ 2, –2 ≤ y ≤ 2,
x2 y2 = ( – – )
[x,y] = meshgrid([-2:.2:2]);
z = x.*exp(-x.^2 - y.^2);
